Reaction Steps

Analogous to the procedure described for Example 1A, Step B, 5-[3-oxo-4-(3-phenoxy-phenyl)-butyl]-pyrrolidin-2-one (923.6 mg, 2.86 mmol) was reduced with NaBH4 (54 mg, 1.4 mmol). Purification by medium pressure chromatography (1:1 hexanes:EtOAc to 2% MeOH in CH2Cl2 to 4% MeOH in CH2Cl2 to 10% MeOH in CH2Cl2) provided 5-[3-hydroxy-4-(3-phenoxy-phenyl)-butyl]-pyrrolidin-2-one (668.3 mg). 1H NMR (CDCl3) δ7.31 (m, 2H), 7.23 (m, 1H), 7.08 (m, 1H), 6.97 (d, 2H), 6.91 (d, 1H), 6.84 (m, 2H), 3.80 (m, 1H), 3.73 (m, 1H), 2.77-2.03 (m, 2H), 2.40 (m, 2H), 2.24 (m, 1H), 1.75-1.41 (m, 5H); MS 326.3 (M+1).
